The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of LM337KC, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
LM337KC Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM337KC is 40V. Exceeding this voltage can cause damage to the device.
-
While the LM337KC can handle up to 1.5A of output current, it's not recommended for high-current applications due to thermal limitations. For high-current applications, consider using a heat sink or a more suitable regulator like the LM338K.
-
The output voltage of the LM337KC can be adjusted by using a resistive divider network between the output pin and the adjust pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula: Vout = 1.25V x (1 + R1/R2).
-
The minimum input voltage required for the LM337KC to operate is 3V above the desired output voltage. For example, if you want an output voltage of 12V, the minimum input voltage should be at least 15V.
-
No, the LM337KC is a linear regulator and is not suitable for switching regulator applications. It's designed to operate in a linear mode, and using it in a switching regulator application can cause instability and oscillations.
